NavalToday has a short piece on the new German F-125 frigate. It is primarily to show the video above, of the frigate firing its 27mm guns and 5″/64 Otobreda.
The unusual aspect of the video is the way the mounts for the 27mm guns lean out (see 1:25). I’m not sure it is worth the complication, but it does permit the gun to fire at targets close alongside near the waterline. It probably means it can be fired on bearings closer to the bow and stern too.
Thanks to Mike R. for bringing this to my attention.

This then upside down………
I think that the mounts that can lean out are the ones armed with a 12.7 mm HMG. Those are OTO Melara’s (now Leonardo) Hitrole: http://www.leonardocompany.com/-/hitrole-n
One would think using the ‘lift’ in the upper handling room for 5″ projectiles would slow the rate of fire. Why not just man handle? Any in shape guy or gal could handle 55 pounds.
These projectiles are a little larger at about 70 pounds, http://www.navweaps.com/Weapons/WNIT_5-64_LW.php
The US equivilent does I believe use old fashion muscle to reload, except that BAE had an automated magazine that is going on the British Type26 frigate.
As far as I know, the lift is related to the weight a german worker can handle under the german labour law.
